Instructions

1

Brown bacon in large pot over medium heat, about 5 minutes. Remove with slotted spoon.

2

Add sausage to bacon fat; break up and brown 6-7 minutes.

💡 Deep brown = key flavour. Don't rush this step.
3

Add onion, cook 3 minutes. Add garlic and red pepper flakes, 30 seconds.

4

Pour in broth; bring to gentle boil. Add cauliflower; simmer 8 minutes until just tender.

8:00
5

Reduce heat to low. Stir in cream and kale. Simmer 4 minutes until kale wilts.

💡 Low heat keeps cream from separating.
6

Off heat, stir in parmesan. Top each bowl with crispy bacon and extra parmesan.

💡 Off-heat parmesan = smooth melt, never lumpy.

Common Questions

Net carbs per serving?
About 6 g — cauliflower 3 g, kale 1 g, cream and onion bring the rest.
Hot or mild sausage?
Either. Hot sausage already adds heat, so skip the red pepper flakes. Mild + flakes is the classic profile.
Substitute for kale?
Spinach (add at the very end, wilts in 30 sec), Swiss chard, or escarole.
Make ahead?
Make through step 4. Cool. Add cream + kale just before serving — they don't warm well after standing.
Freeze?
Freeze without cream and kale. Add them when warming through from frozen.

What to drink with this

🍷
Wine
Chianti Classico or Barbera d'Asti — Italy's medium-bodied reds match tomato acidity perfectly.
🍺
Beer
Italian pilsner like Peroni Nastro Azzurro.
🍸
Cocktail
Aperol Spritz — bitter-sweet aperitif balances rich pasta.
🥤
Non-alcoholic
Sparkling water with lemon and a sprig of basil.

Common mistakes to avoid

The story behind this recipe ▾
Zuppa Toscana is a Tuscan-American restaurant favourite (Olive Garden's signature). The keto version swaps starchy potato for cauliflower and removes flour — same body, identical taste, 6 g net carbs instead of 30 g.
